Semipalmated Plover male and female 5/31/18

I try to avoid bird photos with busy backgrounds like this one, but there’s two interesting things in this image worth pointing out. Most field guides as a rule don’t mention the sexual dimorphism in shorebirds, perpetuating the idea that the sexes look exactly alike. I’m guessing the reason is that shorebirds are already so tricky to ID, they don’t want to push it with even subtler distinctions. But here’s an example of a male and female Semipalmated Plover. Plover and not sandpiper because the bill is short and the body is stockier, and semipalmated because there’s a bit of webbing between the toes (but nothing like say a duck or seagull). Now look at the male bird in the foreground and notice all the black around the face, while in the female behind the black single ringed collar is really dark brown, as is the face mask except for the forehead. The other thing I wanted to point out is a new discovery for me, and that’s the thin but bright yellow eye-ring, which is part of the bird’s breeding plumage that you won’t see when these birds migrate back through in the fall.
